FIELD OF THE DISCLOSURE

The present disclosure generally relates to the field of displaytechnology and, more particularly, relates to a display panel and adisplay device.

BACKGROUND

With the development of display technology, display panels haveincreasingly higher screen-to-body ratios, and full screens havereceived widespread attention due to their narrow or even borderlessdisplay effects. At present, display devices such as mobile phones andtablet computers often need to reserve space for commonly usedelectronic photosensitive devices, such as front cameras, infraredsensing devices, fingerprint recognition devices, etc. For example,these photosensitive devices are arranged on the top of the front of thedisplay device, and the corresponding position forms a non-displayregion, thereby reducing the screen-to-body ratio of the device.

In existing technology, in order to increase the screen-to-body ratio, ahighly light-transmissive region can be opened in the display region ofthe display panel to accommodate the photosensitive devices describedabove.

With the development of full screens, more and more electronicphotosensitive devices need to be integrated under the screen. Forexample, a semi-transparent region is disposed on the display screen,and a camera is disposed under the screen and corresponding to thesemi-transparent region. In normal display, the semi-transparent regioncan be used for display; and when taking photos or videos is needed, thecamera may take photos or videos through the semi-transparent region, sothat the semi-transparent region can realize the functions of displayand picture-taken simultaneously. How to simplify the production processwhile achieving high transmittance in the semi-transparent region hasbecome one of the technical problems that need to be solved immediatelyat this stage. The disclosed display panel and display device aredirected to solve one or more problems set forth above and otherproblems in the art.

The present disclosure provides a display panel. FIG. 1 illustrates aschematic structural diagram of an exemplary display panel according tovarious embodiments of the present disclosure, and FIG. 2 illustrates aschematic diagram of an exemplary relative position relationship betweena semi-transparent region and pixel driving circuits in thesemi-transparent region. Referring to FIGS. 1-2 , the display panel 100may include a display region AA and a non-display region NA. The displayregion AA may include a first display region AA1 and at least one seconddisplay region AA2. The first display region AA1 may at least surroundthe second display region AA2. The second display region AA2 may includeat least two semi-transparent regions 10 and a spacing region 11 locatedbetween two adjacent semi-transparent regions 10. The display region AAmay include a plurality of sub-pixels P and a plurality of pixel drivingcircuits 30 electrically connected to the plurality of sub-pixels P. Thepixel driving circuits 30 electrically connected to the sub-pixels P inthe semi-transparent region 10 may be at least partially located in thefirst display region AA1 and the spacing region 11.

It should be noted that FIG. 1 only shows a case where the display panel100 includes one second display region AA2. In other embodiments of thepresent disclosure, according to actual needs, two or more seconddisplay regions AA2 may be provided on the display panel 100, and thequantity of the second display regions AA2 included in the display panelis not specifically defined in the present disclosure. In the following,as an example, the display panel 100 is described to include one seconddisplay region AA2 for illustration, and when the display panel 100includes multiple second display regions AA2, the display panel 100 maybe implemented with reference to various embodiments of the presentdisclosure.

Further, FIG. 1 only illustrates a case where the first display regionAA1 completely surrounds the second display region AA2. In some otherembodiments of the present disclosure, the first display region AA1 mayhalf or partially surround the second display region AA2.

FIG. 1 also only shows a relative position relationship between thefirst display region AA1 and the second display region AA2 in thedisplay panel 100. In some other embodiments of the present disclosure,the second display region AA2 may be located at any other position inthe display panel 100, which is not specifically defined in the presentdisclosure.

Moreover, the circular shape of the semi-transparent region 10 in FIGS.1-2 is also only for illustration. In some other embodiments of thepresent disclosure, the semi-transparent region 10 may have other shape,such as a rectangular shape, an elliptic shape, etc. the size of thesemi-transparent region 10 is not specifically limited in the presentdisclosure and may be set according to actual needs.

FIG. 2 only shows a schematic diagram of the arrangement of sub-pixelsin the semi-transparent region 10, and does not represent the actualquantity and size of the sub-pixels. In order to clearly reflect theconnection relationship between the sub-pixels in the semi-transparentregion and the pixel driving circuits, FIG. 2 does not show thearrangement of sub-pixels in the spacing region 11 and the first displayregion AA1. The arrangement of sub-pixels in the spacing region 11 andthe first display region AA1 is not specifically defined in the presentdisclosure, and for examples, reference may be made to the arrangementof sub-pixels in existing display panels.

It should be understood that FIGS. 1-2 only take one second displayregion AA2 including two semi-transparent regions 10 and one spacingregion 11 as an example for illustration. In some other embodiments ofthe present disclosure, one second display region AA2 may include threeor more semi-transparent regions 10, and a spacing region 11 may beprovided between any two adjacent semi-transparent regions 10. In thepresent disclosure, only a case where a display region AA2 includes twosemi-transparent regions 10 is provided as an example for illustration.When a second display region AA2 includes three or more semi-transparentregions 10, along the arrangement direction of the semi-transparentregions, a spacing region may be disposed between any two adjacentsemi-transparent regions. The pixel driving circuits corresponding tothe sub-pixels may be located in the two spacing regions on both sidesof the semi-transparent region, or in the first display region adjacentto the semi-transparent region, and the arrangement of the pixel drivingcircuits is not specifically defined in the present disclosure.

In addition, the present disclosure only uses an example wheresemi-transparent regions included in a same second display region have asame shape and a same size for illustration. In some other embodimentsof the present disclosure, the semi-transparent regions included in asame second display region may have different shapes and/or differentsizes, which are not specifically defined in the present disclosure.

For example, FIG. 3 illustrates a schematic diagram of another exemplaryrelative position relationship between a semi-transparent region andpixel driving circuits in the semi-transparent region. Referring to FIG.3 , the two semi-transparent regions 10 may have different shapes. Onesemi-transparent region 10 may have a triangular shape, and the othersemi-transparent region 10 may have a circular shape. The sizes of thetwo semi-transparent regions 10 may also be different. The pixel drivingcircuits 30 electrically connected to the sub-pixels P in each of thetwo semi-transparent regions 10 may be arranged in the first displayregion AA1 and the spacing region 11.

FIG. 4 illustrates a schematic diagram of another exemplary relativeposition relationship between a semi-transparent region and pixeldriving circuits in the semi-transparent region. Referring to FIG. 4 ,in another example, the two semi-transparent regions 10 may have a sameshape but different sizes. The pixel driving circuits 30 electricallyconnected to the sub-pixels P in each of the two semi-transparentregions 10 may be arranged in the first display region AA1 and thespacing region 11.

Further, referring to FIGS. 1-4 , the display panel 100 according tovarious embodiments of the present disclosure may be provided with afirst display region AA1 and at least one second display region AA2. Thefirst display region AA1 may at least partially surround the seconddisplay region AA2, and the second display region AA2 may include twosemi-transparent regions 10 and a spacing region 11 disposed between thetwo adjacent semi-transparent regions 10. During a display stage, thesemi-transparent region 10 and the spacing region 11 in the seconddisplay region AA2 may both display; and during a picture-taken stage,the semi-transparent region 10 in the second display region AA2 mayserve as a light-transmissive region to implement the photographyfunction.

According to various embodiments of the present disclosure, both thefirst display region AA1 and the second display region AA2 are providedwith a plurality of sub-pixels. It should be noted that, in order toclearly illustrate the principle and content of the present disclosure,FIG. 2 only shows a part of the sub-pixels in the semi-transparentregion 10, and a part of the pixel driving circuits 30 in the spacingregion 11 and the first display region AA1. The sub-pixels of thespacing region 11 and the first display region AA1 are not shown. Itshould be understood that sub-pixels are provided in both the spacingregion 11 and the first display region AA1, and the sub-pixels in thefirst display region AA1 and the second display region AA2 areelectrically connected to the pixel driving circuits 30, such that thesub-pixels can be driven by the pixel driving circuits 30 to display.

It should be noted that the pixel driving circuits 30 electricallyconnected to the sub-pixels may be implemented by any appropriate pixeldriving circuits in existing technology, such as the 7T1C drivingcircuits, etc. which is not specifically defined in the presentdisclosure. The present disclosure introduces a spacing region 11between two adjacent semi-transparent regions 10, and disposes at leasta part of the pixel driving circuits 30, that are electrically connectedto the sub-pixels in the semi-transparent region 10, in the firstdisplay region AA1 and the spacing region 11. Therefore, reduction ofthe transmittance of the semi-transparent region 10 due to arrangementof the pixel driving circuits 30 in the semi-transparent region 10 maybe avoided, which is conducive to increasing the transmittance of thesemi-transparent region 10 and improving the photographic quality.

In one embodiment of the present disclosure, no pixel driving circuit 30may be provided in each semi-transparent region 10 of the display panel100, but the corresponding pixel driving circuits 30 may be provided inthe first display region AA1 and the spacing region 11. As such, thetransmittance of the semi-transparent region 10 may be further improved.Because the pixel driving circuits 30 and the sub-pixels P need to beelectrically connected through lead wires, in one embodiment of thepresent disclosure, a spacing region 11 may be introduced betweenadjacent semi-transparent regions 10. In addition, the pixel drivingcircuits 30 electrically connect the sub-pixels in the semi-transparentregions 10 may be partially disposed in the first display region AA1 andpartially disposed in the spacing region 11. As such, the wiresconnecting the pixel driving circuits 30 and the sub-pixels P in thesemi-transparent region 10 may extend from the first display region AA1and the spacing region 11 to the semi-transparent region 10, which isconducive to reducing the wiring density, and further beneficial toreducing crosstalk between adjacent lead wires in the semi-transparentregion 10.

In addition, in order to realize the display function, the pixel drivingcircuits are usually electrically connected with the data lines, andthus the data signals may be obtained through the data lines. Accordingto the present disclosure, when the pixel driving circuits correspondingto the sub-pixels in the semi-transparent region are disposed in thefirst display region AA1 and the spacing region 11, the windingphenomenon of the data lines that are electrically connected to thepixel driving circuits is reduced, which is conducive to reducing theload on the data lines.

In some examples, when the pixel driving circuits 30 corresponding tothe sub-pixels in the semi-transparent region 10 are collectivelyarranged in the first display region AA1, the lead wires between thesub-pixels in the semi-transparent region 10 and the pixel drivingcircuits 30 may be gathered between the first display region AA1 and thesemi-transparent region 10. To avoid short circuits due to leadaggregation, these lead wires may be arranged in different film layers.When these lead wires are arranged in different film layers, the wiresin different film layers may correspond to different manufacturingprocesses, which may increase the process complexity and may not beconductive to saving production cost.

Therefore, in some embodiments, referring to FIGS. 2-4 , a part of thesub-pixels in the semi-transparent region 10 may be electricallyconnected to the pixel driving circuits 30 in the first display regionAA1 through first lead wires L1, and the other part of the sub-pixels inthe semi-transparent region may be electrically connected to the pixeldriving circuits 30 in the spacing region through second lead wires L2.The first lead wires L1 and the second lead wires L2 may be arranged ina same layer.

For example, when the pixel driving circuits 30 electrically connectedto the sub-pixels in the semi-transparent region 10 is disposed in thefirst display region AA1 and the spacing region 11, a part of thesub-pixels in the semi-transparent region 10 may be connected to thefirst display region through the first lead wires L1, and the other partof the sub-pixels in the semi-transparent region 10 may be connected tothe pixel driving circuits 30 in the first display region AA1 throughthe second lead wires L2. Further, the first lead wires L1 and thesecond lead wires L2 may be arranged in a same layer. At this time, thefirst lead wires L1 and the second lead wires L2 may be made in a samemanufacturing process using a same mask. There is no need to introducedifferent manufacturing processes for the first lead wires L1 and thesecond lead wires L2. The electrical connections between the sub-pixelsof the semi-transparent region 10 and the corresponding pixel drivingcircuits 30 may be completed by using a single-layer wire, therebyreducing the number of processes, reducing the manufacturing time of theproducts, and improving the production efficiency of the display panel100. Further, it may also be conducive to reducing the cost for maskfabrication and saving the production cost.

FIG. 5 illustrates a schematic diagram of connections between sub-pixelsin a semi-transparent region and first and second lead wires. Referringto FIG. 5 , in another example, the line segment of each first lead wireL1 located in the semi-transparent region 10 may be set into an arcshape, and the line segment of each second lead wire L2 located in thesemi-transparent region 10 may be set into an arc shape.

For example, when the sub-pixels in the semi-transparent region 10 areconnected to the corresponding pixel driving circuits 30 in the firstdisplay region AA1 or the spacing region 11 through the first lead wiresL1 or the second lead wires L2, each first lead wire L1 and each secondlead wire L2 may both include a line segment located in thesemi-transparent region 10 and a line segment located in the firstdisplay region AA1 or the spacing region 11. When the lead wires arearranged in the semi-transparent region 10, gaps may be formed betweenadjacent lead wires. The presence of the gaps may likely cause lightdiffraction problems, and the diffraction problems may easily lead tothe taken pictures unclear. Also, when there is a straight-line boundaryin the semi-transparent region 10 (for example, when the lead wire is astraight line), the phenomenon of the diffraction superposition may takeplace, thereby greatly affecting the photographic quality. According tovarious embodiments of the present disclosure, when the line segment ofeach first lead wire L1 or each second lead wire L2 located in thesemi-transparent region 10 is set into an arc shape, the degree ofdiffraction in the semi-transparent region 10 can be greatly reduced,thereby reducing the effect of diffraction on the pictures taken. Assuch, setting the line segments of the first lead wires L1 and thesecond lead wires L2 located in the semi-transparent region 10 into arcshapes may be conducive to improving the clarity of the pictures takenand improving the photographic quality.

In one embodiment, to further suppress the diffraction problems of thesemi-transparent region 10, the shape of the sub-pixels in thesemi-transparent region 10 may also be set to a shape that includes anarc (e.g., the boundary of the semi-transparent region 10 may include atleast one arc), such as a circle as shown in FIGS. 3-5 . It should benoted that when the display panel 100 according to the presentdisclosure is an organic light-emitting display (OLED) panel, the shapeof the sub-pixel may refer to the shape of the anode corresponding tothe sub-pixel, and when the display panel 100 according to the presentdisclosure is a liquid crystal display panel, the shape of the sub-pixelmay refer to the shape of an opening region of the liquid crystal panel.

In one embodiment of the present disclosure, the first lead wires L1 andthe second lead wires L2 may all be transparent lead wires. For example,making the first lead wires L1 and the second lead wires L2 astransparent conductive wires, for example, using indium tin oxide (ITO)or any other appropriate transparent material to form the first leadwires L1 and the second lead wires L2, may be conducive to reducing theshielding degree of the line segments of the first lead wires L1 and thesecond lead wires L2 in the semi-transparent region 10, thereby helpingto further enhance the transmittance of the semi-transparent region 10,and improving the photographic quality when taking pictures through thedisplay panel 100.

FIG. 6 illustrates a schematic diagram of an exemplary pixel arrangementin a regular region, a transition region, and a second display regionaccording to various embodiments of the present disclosure. Referring toFIGS. 5-6 , the first display region AA1 may include a regular region 20and a transition region 21. The transition region 21 may be locatedbetween the regular region 20 and the second display region AA2. Thepixel density of the regular region 20 may be greater than or equal tothe pixel density of the transition region 21, and the pixel density ofthe transition region 21 may be greater than or equal to the pixeldensity of the semi-transparent region 10. The pixel density of thespacing region 11 may be greater than or equal to the pixel density ofthe semi-transparent region 10, and the pixel density of the spacingregion 11 may be greater than or equal to the pixel density of thetransition region 21. Further, the pixel driving circuits 30 located inthe first display region AA1 and electrically connected to thesub-pixels in the semi-transparent region 10 may be located in thetransition region 21.

For example, referring to FIGS. 5-6 , the first display region AA1 maybe provided with a regular region 20 and a transition region 21. Thetransition region 21 may be located between the regular region 20 andthe second display region AA2. The pixel density of the transitionregion 21 may be less than the pixel density of the regular region 20,and the pixel density of the transition region 21 may be greater thanthe pixel density of the semi-transition region 10. When the pixeldriving circuits 30 are fabricated in the regular region 20 and thetransition region 21, the pixel driving circuits 30 are usually formedaccording to a same arrangement density in the regular region 20 and thetransition region 21. When the pixel density of the transition region 21is less than the pixel density of the regular region 20, in a same unitarea, the quantity of pixel driving circuits 30 required for driving thesub-pixels in the transition region 21 may be smaller than the quantityof pixel driving circuits 30 required for driving the sub-pixels in theregular region 20. As such, the transition region 21 may have more pixeldriving circuits 30 than sub-pixels, and the extra pixel drivingcircuits 30 may be used as pixel driving circuits for driving thesub-pixels in the semi-transparent region 10 to emit light. In addition,according to the present disclosure, because the pixel density of thesemi-transparent region 10 and the regular region is very different, thepixel density of the sub-pixels in the transition region 21 may be setto be greater than the pixel density of the sub-pixels in thesemi-transparent region 10 but less than the pixel density of thesub-pixels in the regular region 20. The transition region 21 may beable to realize the transition of the pixel density between thesemi-transparent region 10 and the regular region 20, thereby avoidingobvious uneven display due to the large difference in the pixel densitybetween the semi-transparent region 10 and the regular region 20 duringthe display stage. Therefore, the setting of the pixel density of thetransition region 21 may also be conducive to improving the displayuniformity of the display panel 100 during the display stage.

FIG. 7 illustrates a schematic diagram of another exemplary pixelarrangement in a regular region, a transition region, and a seconddisplay region according to various embodiments of the presentdisclosure. Referring to FIG. 7 , in one embodiment of the presentdisclosure, in a direction from the second display region AA2 to thefirst display region AA1, the pixel density of the transition regionincreases.

For example, the pixel density of the transition region 21 may bedesigned in a gradual manner, so that in a direction F pointing from thesecond display region AA2 to the first display region AA1, the pixeldensity of the transition region 21 may show an increasing trend. Thatis, from the semi-transparent region 10 to the regular region 20, thepixel density of the transition region 20 may be increasing. The pixeldensity of the part of the transition region 21 close to thesemi-transparent region 10 may be close to the pixel density of thesemi-transparent region 10, and the pixel density of the part of thetransition region 21 close to the regular region 20 may be close to thepixel density of the regular region 20. As such, the gradual change inthe pixel density of the transition region 21 may be conducive toreducing the display difference between the transition region and thesemi-transparent region 10, and at the same time, the gradual change inthe pixel density of the transition region 21 may also be conducive toreducing the display difference between the transition region and theregular region 20. Therefore, the gradual change in the pixel density ofthe transition region 21 may be conducive to further improving thedisplay uniformity of the display panel 100 during the display stage.

FIG. 8 illustrates a schematic diagram of connections between sub-pixelsin a semi-transparent region and corresponding pixel driving circuits inthe transition region. It should be noted that FIG. 8 only shows anarrangement of the pixel driving circuits 30 (including a plurality offirst pixel driving circuits 31 and a plurality of second pixel drivingcircuits 32) in the transition region 21, and does not show thesub-pixels in the transition region 21. In actual applications, thetransition region 21 is provided with a plurality of sub-pixelselectrically connected to the first pixel driving circuits 31 in aone-to-one correspondence for implementing the display function of thetransition region 21.

Referring to FIG. 8 , in one embodiment of the present disclosure, thepixel driving circuits 30 in the transition region 21 may include aplurality of first pixel driving circuits 31 and a plurality of secondpixel driving circuits 32. The first pixel driving circuits 31 may beelectrically connected to the sub-pixels in the transition region 21 ina one-to-one correspondence, and the second driving circuits 32 may beelectrically connected to the sub-pixels in the semi-transparent region10. The first pixel driving circuits 31 may be arranged in an arrayalong a first direction D1 and a second direction D2, and each secondpixel driving circuit 32 may be arranged between two adjacent firstpixel driving circuits 31 along the first direction D1 and/or the seconddirection D2. The first direction D1 and the second direction D2 mayintersect each other.

It should be noted that, to clearly distinguish the first pixel drivingcircuits 31 and the second driving circuits 32, the first pixel drivingcircuits 31 and the second pixel driving circuits 32 are illustrated indifferent filling patterns in FIG. 8 . In actual applications, the firstpixel driving circuits 31 and the second pixel driving circuits 32 maybe formed with the same structure. When fabricating the pixel drivingcircuits in the display region, usually a plurality of pixel drivingcircuits arranged in an array is made in the entire display region.Because the pixel density of the transition region is less than thepixel density of the regular region, in the same unit area, the quantityof pixel driving circuits required by the transition region may be less.That is, a part of the pixel driving circuits in the transition region21 can be used as the first pixel driving circuits 31 for driving thesub-pixels in the transition region 21, and the other part of the pixeldriving circuits in the transition region 21 can be electronicallyconnected to the sub-pixels in the semi-transparent region 10 and thusserve as a plurality of second pixel driving circuits 32 for driving thesub-pixels in the semi-transparent region 10.

FIG. 9 illustrates another schematic diagram of connections betweensub-pixels in a semi-transparent region and corresponding pixel drivingcircuits in a transition region. Referring to FIG. 9 , when the secondpixel driving circuits 32 in the transition region 21 are electricallyconnected to the sub-pixels in the semi-transparent region 10, among thesecond pixel driving circuits 32 in the transition region 21, the secondpixel driving circuits 32 close to the semi-transparent region 10 alongthe first direction D1 may be electrically connected to the sub-pixelsof the semi-transparent region 10 far away from the transition region21, and the second pixel driving circuits 32 far away from thesemi-transparent region 10 may be electrically connected to thesub-pixels of the semi-transparent region 10 close to the transitionregion 21. As such, the design may be conducive to reducing the lengthdifference of the first lead wires L1 connecting the sub-pixels to thesecond pixel driving circuits 32, and avoiding the large difference inthe load due to the large difference in the length of the first leadwires L1. Therefore, the design may be conducive to improving theuniformity of the display brightness of the sub-pixels in thesemi-transparent region 10, and improving the display effect of thesemi-transparent region 10.

FIG. 10 illustrates a schematic diagram of connections betweensub-pixels in a semi-transparent region and corresponding pixel drivingcircuits in a spacing region. Referring to FIG. 10 , the pixel drivingcircuits 30 in the spacing region 11 may include a plurality of thirdpixel driving circuits 33 and a plurality of fourth pixel drivingcircuits 34. The third pixel driving circuits 33 may be electricallyconnected to the sub-pixels in the spacing region 11 in a one-to-onecorrespondence. It should be noted that, to clearly distinguish thethird pixel driving circuits 33 and the fourth driving circuits 34, thethird pixel driving circuits 33 and the fourth pixel driving circuits 34are illustrated in different filling patterns in FIG. 10 . In actualapplications, the third pixel driving circuits 33 and the fourth pixeldriving circuits 34 may be formed with the same structure.

Referring to FIG. 10 , The third pixel driving circuits 33 may bearranged in an array along a first direction D1 and a second directionD2, and each fourth pixel driving circuit 34 may be arranged between twoadjacent third pixel driving circuits 33 along the first direction D1and/or the second direction D2. The first direction D1 and the seconddirection D2 may intersect each other.

Along the first direction D1, the spacing region 11 may be locatedbetween two semi-transparent region 10. The spacing region 11 mayinclude a first spacing region 111 and a second spacing region 112arranged along the first direction D1. The first spacing region 111 maybe adjacent to one semi-transparent region 10, and the second spacingregion 112 may be adjacent to the other semi-transparent region 10. Thefourth pixel driving circuits 34 of the first spacing region 111 may beelectrically connected to the sub-pixels of the semi-transparent region10 adjacent to the first spacing region 111, and the fourth pixeldriving circuits 34 of the second spacing region 112 may be electricallyconnected to the sub-pixels of the semi-transparent region 10 adjacentto the second spacing region 112.

For example, referring to FIG. 10 , because the spacing region 11 islocated between two semi-transparent regions 10, in one embodiment, thespacing region 11 may be divided into a first spacing region 111 and asecond spacing region 112, and the first spacing region 111 and a secondspacing region 112 may be respectively adjacent to the twosemi-transparent regions 10. That is, one semi-transparent region 10 maybe located on the side of the first spacing region 111 away from thesecond spacing region 112, and the other semi-transparent region 10 maybe located on the side of the second spacing region 112 away from thefirst spacing region 111. The fourth pixel driving circuits 34corresponding to a part of the sub-pixels of the semi-transparent region10 adjacent to the first spacing region 111 may be disposed in the firstspacing region 111, and the fourth pixel driving circuits correspondingto a part of the sub-pixels of the semi-transparent region 10 adjacentto the second spacing region 112 may be disposed in the second spacingregion 112. As such, the fourth pixel driving circuits 34 of the spacingregion 11 may be electrically connected to the sub-pixels in thesemi-transparent region 10 in a close-connection manner, which may beconducive to simplifying the wiring process of the display panel 100.

It should be noted that FIG. 10 only shows an arrangement of the pixeldriving circuits 30 in the spacing region 11, and does not show thesub-pixels in the spacing region 11. In actual applications, the spacingregion 11 is provided with a plurality of sub-pixels electricallyconnected to the third pixel driving circuits 33 in a one-to-onecorrespondence for implementing the display function of the spacingregion 11. The third pixel driving circuits 33 and the fourth pixeldriving circuits 34 may be together arranged in an array along the firstdirection D1 and the second direction D2.

It should be understood that when the fourth pixel driving circuits 34in the first spacing region 111 are electrically connected to thesub-pixels in the semi-transparent region 10, among the fourth pixeldriving circuits 34 in the first spacing region 111, the fourth pixeldriving circuits 34 close to the semi-transparent region 10 may beelectrically connected to the sub-pixels in the semi-transparent region10 that are far away from the first spacing region 111, and the fourthpixel driving circuits far away from the semi-transparent region 10 maybe electrically connected to the sub-pixels in the semi-transparentregion 10 that are close to the first spacing region 111. The fourthpixel driving circuits 34 in the second spacing region 112 and thesub-pixels in the semi-transparent region 10 may also adopt similardesigns. Therefore, the design may be conducive to reducing the lengthdifference of the second lead wires L2 connecting the sub-pixels to thecorresponding fourth pixel driving circuits 34, and avoiding the largedifference in the load due to the large difference in the length of thesecond lead wires L2. Therefore, the design may be conducive toimproving the uniformity of the display brightness of the sub-pixels inthe semi-transparent region 10, and improving the display effect of thesemi-transparent region 10.

It should be noted that the embodiments illustrated in FIGS. 2-7 show asituation where the pixel driving circuits 30 corresponding to thesub-pixels in the semi-transparent region 10 are provided in thetransition region 21 and the spacing region 11 on both sides of thesemi-transparent region 10 along the first direction D1, and in otherembodiments, when the pixel driving circuits connected to the sub-pixelsin the semi-transparent region 10 are provided in the transition region21, the pixel driving circuits 30 may be located in the transitionregion 21 on both side of the semi-transparent region 10 along thesecond direction D2.

FIG. 11 illustrates another schematic diagram of connections betweensub-pixels in a semi-transparent region and corresponding pixel drivingcircuits in a transition region. Referring to FIG. 11 , the pixeldriving circuits 30 may be located in the transition region 21 on bothside of the semi-transparent region 10 along the second direction D2.The arrangement shown in FIG. 11 may be more conducive to avoiding theaggregation of the first lead wires L1 that connect the sub-pixels inthe semi-transparent region 10 to the pixel driving circuits 30 in thetransition region 21. As such, when realizing the arrangement of thefirst lead wires L1 and the second lead wires L2 in the same layer, thedesign may also be conducive to reducing the wiring difficulty of thefirst lead wires L1.

FIG. 12 illustrates a schematic diagram of an exemplary relativeposition relationship between a semi-transparent region and a transitionregion and between the semi-transparent region and a spacing region.Referring to FIG. 12 , in a same second display region AA2, thesemi-transparent region 10 and the spacing region 11 may be arrangedalong the first direction D1. The first display region AA1 may include aregular region 20 and a transition region 21. The transition region 21may be located between the regular region 20 and the second displayregion AA2. The transition region 21 may include at least one firsttransition region 211 and at least one second transition region 212. Theat least first transition region 211 may be arranged on at least oneside of the second display region AA2 along a second direction D2, andthe at least one second transition region 212 may be arranged on atleast one side of the second display region AA2 along a first directionD1. The first direction D1 and the second direction D2 may intersecteach other. The pixel driving circuits 30 located in the first displayregion AA1 and electrically connected to the sub-pixels in thesemi-transparent region 10 may be located in the second transitionregion 212.

It should be noted that FIG. 12 only takes the second display region AA2including two semi-transparent regions 10 and one spacing region 11 asan example for illustration. In one embodiment, the transition region 21may include two first transition regions 211 oppositely disposed on thetwo sides of the second display region AA2 along the first direction D1and two second transition regions 212 oppositely disposed on the twosides of the second display region AA2 along the second direction D2. Itshould e noted that both the first transition regions 211 and the secondtransition regions 212 are provided with sub-pixels. In order to clearlyreflect the connection relationship between the sub-pixels in thesemi-transparent region 10 and the pixel driving circuits 30, the figuredoes not show the sub-pixels arranged in the first transition region 211and the second transition region 212. The pixel driving circuits 30arranged in the first display region AA1 and electrically connected tothe sub-pixels in the semi-transparent region 10 may be located in thesecond transition region 212. In the viewing angle shown in FIG. 12 ,the pixel driving circuits 30 in the transition region 21 electricallyconnected to the sub-pixels in the semi-transparent region may belocated in the transition region 21 on the left or right side of thesemi-transparent region 10, that is, located in the second transitionregion 212 opposite to the spacing region 11. As such, the design may beequivalent to arranging the pixel driving circuits 30 that are connectedto the sub-pixels in the semi-transparent region 10 on opposite sides ofthe semi-transparent region 10 along the first direction D1. At thistime, the first lead wires L1 and the second lead wires L2 may togethertend to extend in the first direction D1, which may be conducive toavoiding the winding phenomenon that may occur when the first lead wiresL1 and the second lead wires L2 extend in different directions.

FIG. 13 illustrates a schematic diagram of a plurality of lead wireslocated between a semi-transparent region and a transition region andbetween the semi-transparent region and a spacing region. Referring toFIG. 13 , the first transition region 211 may include a plurality offirst signal lines 41 extending along the first direction D1 andarranged along the second direction D2. The pixel driving circuits 30located in the spacing region 11 may be electrically connected to thefirst signal lines 41.

Referring to FIG. 13 , in one embodiment, each second display region ofthe at least one second display region includes at least twophotosensitive device setting regions and a spacing region disposedbetween the at least two adjacent photosensitive device setting regions.The display region is provided with a plurality of sub-pixels and pixeldriving circuits electrically connected to the plurality of sub-pixels.The pixel driving circuits corresponding to the plurality of sub-pixelsin the spacing region are electrically connected to the pixel drivingcircuits located in the first display region through signal lead wires.

Referring to FIG. 13 , in one embodiment, a plurality of first signallines extending along the first direction and arranged along a seconddirection, wherein the pixel driving circuits located in a same row inthe first display region and the second display region are electricallyconnected through the first signal lines and the signal lead wires.

Referring to FIG. 13 , in one embodiment, the pixel driving circuitslocated in a same row in the spacing region correspond to the signallead wires. A part of the signal lead wires is located at a first sideof the sub-pixel rows, and another part of the signal lead wires islocated at a second side of the sub-pixel rows

Referring to FIG. 13 , in one embodiment, the at least twophotosensitive device setting regions are semi-transparent regions. Thepixel driving circuits that are electrically connected to the pluralityof sub-pixels in the semi-transparent regions at least partially locatedin the first display region and the spacing region.

For example, because the spacing region 11 is provided with pixeldriving circuits 30 for driving the sub-pixels in the spacing region 11to emit light, and at the same time, also provided with pixel drivingcircuits 30 for driving the sub-pixels in the semi-transparent region 10to emit light, in order to realize the normal operation of these pixeldriving circuits, the pixel driving circuits 30 may need to be connectedto signal lead wires to realize signal transmission. According to oneembodiment of the present disclosure, the first signal lines 41connected to the pixel driving circuits 30 in the spacing region 11 maybe arranged in the first transition region 211, and the first signallines 41 may extend in the first transition region 211 along the firstdirection D1 and arranged along the second direction D2. As such, thefirst signal lines 41 may not need to be arranged around thesemi-transparent region 10, but extend long the first direction 10 inthe first transition region 211 to achieve electrical connections withthe pixel driving circuits 30 in the spacing region 11. Compared withthe form in which the first signal lines are arranged in the spacingregion 11, the design according to the present disclosure is equivalentto moving the first signal lines 41 in the spacing region 11 outward, sothat the spacing region 11 may save space for arranging pixel drivingcircuits 30 to connect the sub-pixels in the semi-transparent region 10.

In one embodiment, the first signal lines 41 may be distributed in twofirst transition regions oppositely arranged on the two sides of thesemi-transparent region o10 long the second direction D2, e.g.,distributed on the upper and lower sides of the semi-transparent region10 in the viewing angle shown in FIG. 13 . The pixel driving circuits 30in the spacing region 11 close to the first transition region 211 and onthe upper side of the spacing region 11 may be electrically connected tothe first signal lines 41 located on the upper side of the spacingregion 11, and the first signal lines 41 in the spacing region 11 closeto the first transition region 211 and on the lower side of the spacingregion 11 may be electrically connected to the first signal lines 41 onthe lower side of the spacing region 11. As such, the connectioncomplexity of the pixel driving circuits 30 and the first signal lines41 in the spacing region may be reduced.

In one embodiment of the present disclosure, the plurality of firstsignal lines 41 shown in FIG. 13 may include at least one of a gateline, a light-emission control signal line, and a reset signal line. Thepixel driving circuit usually includes a plurality of transistors, whichneed to be provided with different signals. For example, a signal forcontrolling a transistor to turn on or turn off may be provided to thecontrol terminal of the transistor through a gate line; when atransistor is used as a light-emitting control switch, a light-emittingcontrol signal may be provided to the control terminal of the transistorthrough a light-emitting control signal line; when a transistor is usedas a reset module, a reset signal may be provided to the transistorthrough a reset signal line, etc.

In another embodiment of the present disclosure, referring to FIG. 13 ,the sub-pixels in the spacing region 11 may be arranged in an arrayalong the first direction D1 and the second direction D2. The pixeldriving circuits corresponding to the sub-pixels in a same row may beelectrically connected to a same first signal line 41 through a samesignal lead wire 40. The signal lead wires 40 may extend along thesecond direction D2.

It should be noted that FIG. 13 only shows the sub-pixels in the spacingregion 11, and does not show the pixel driving circuits in the spacingregion 11. In actual applications, the spacing region 11 is providedwith a plurality of pixel driving circuits 30, and the arrangement ofthe plurality of pixel driving circuits 30 may refer to FIG. 12 . Eachsub-pixel in the spacing region 11 may be electrically connected to apixel driving circuit 30 in the spacing region 11. In one example, thefirst signal line 41 may be electrically connected to a second signalline 42 in the first display region AA1. The sub-pixels in the spacingregion 11 may be arranged in an array along the first direction D1 andthe second direction D2. When the pixel driving circuits 30 areelectrically connected to the corresponding first signal lines 41, for apart of the sub-pixel rows in the spacing region 11, each sub-pixel rowmay be arranged in a same row with a sub-pixel row in the first displayregion AA1. That is, for some sub-pixel rows in the spacing region 11,each sub-pixel row may be aligned with a corresponding sub-pixel row inthe first display region AA1. At this time, the pixel driving circuits30 corresponding to the sub-pixels in the same row in the spacing region11 and the first display region AA1 may be electrically connected to afirst signal line 41 and a second signal line 42 that are electricallyconnected to each other. As such, even when the first signal line 41 isrouted on the upper side or the lower side of the semi-transparentregion 10, the driving chip may still be ensured to provide signals tosub-pixels in the same pixel row in the spacing region 11 and the firstdisplay region AA1 according to the original timing.

In addition, the sub-pixels in the same row in the spacing region 11 maybe electrically connected to the same first signal line 41 through asignal lead wire 40, and the signal transmitted from the same firstsignal line 41 may be transmitted to each of the pixel driving circuits30 corresponding to the same row of sub-pixels through the signal leadwire 40. As such, the design may be conducive to reducing the quantityof the signal lead wires 40 for connecting the plurality of first signallines 41 to the pixel driving circuits 30, which may be conducive toreducing the space occupied by the signal lead wires 40 in the spacingregion 11. Therefore, the design may be conducive to reducing the sizeof the spacing region 11. When the size of the spacing region 11 issmall, the overall display uniformity of the display panel may befurther improved.

It should also be noted that the pixel driving circuits 30 correspondingto the sub-pixels in the same row in the spacing region may need to beelectrically connected to a plurality of first signal lines 41 at thesame time. FIG. 13 shows a case where the pixel driving circuits 30corresponding to the sub-pixels in a same row in the spacing regionrespectively connected to four first signal lines 41. In addition, thecase shown in FIG. 13 only takes the spacing region 11 including fourrows of sub-pixels as an example for illustration. In actualapplications, the spacing region 11 may include more sub-pixel rows, andthe present disclosure does not specifically limit the quantity ofsub-pixel rows. The pixel driving circuits 30 corresponding to thesub-pixels in different rows in the spacing region 11 may berespectively connected to different first signal lines 41. For the samefirst signal line 41, the first signal line 41 may be connected to thepixel driving circuits corresponding to a row of sub-pixels through asignal lead wire 40 extending in the second direction D2.

Referring to FIG. 13 , in one embodiment, in the spacing region 11, thesignal lead wires 40 may be arranged on both sides of the sub-pixel rowalong the first direction D1. For example, in the spacing region 11, thepixel driving circuits 30 corresponding to sub-pixels in a same row maybe electrically connected to a plurality of first signal lines 41respectively though a plurality of signal lead wires 40. The quantity ofthe signal lead wires 40 may correspond to the quantity of the firstsignal lines 41. When a plurality of sub-pixel rows is formed in thespacing region 11, the quantity of corresponding first signal lines 41and the quantity of corresponding signal lead wires 40 may be bothlarge. According to one embodiment of the present disclosure, arrangingthe signal lead wires 40 on both sides of the sub-pixel row along thefirst direction D1 may be conducive to avoiding the phenomenon that thesignal lead wires 40 gather on one side of the sub-pixel row, and thusmay be conducive to making efficient use of the spacing region 11 andmaking the space of the spacing region more uniform on both sides alongthe first direction D1.

FIG. 14 illustrates a schematic diagram of an exemplary relativeposition relationship between a first signal line and a signal lead wirethat is electrically connected to the first signal line. Referring toFIG. 14 , in one embodiment, the signal lead wire 40 and the firstsignal line 41 may be disposed in different film layers. When the signallead wire 40 and the first signal line 41 are disposed in different filmlayers, the signal lead wire 40 and the first signal line 41 may beconnected through a via K. The introduction of the signal lead wire 40may not occupy the space of the film layer where the first signal line41 is located, thereby conducive to improving the flexibility of thearrangement of the signal lead wire 40. In addition, the design may alsobe conducive to avoiding forming electrical connections between the samesignal lead wire 40 and other first signal lines 41, thereby improvingthe reliability of the electrical connection between the signal leadwire 40 and the first signal line 41.

FIG. 15 illustrates another schematic diagram of a plurality of leadwires located between a semi-transparent region and a transition regionand between the semi-transparent region and a spacing region. Referringto FIG. 15 , along the second direction D2, two first transition regions211 may be respectively provided on both sides of each of the twosemi-transparent regions 10. In one embodiment, the pixel density in thetransition region 211 may be the same as the pixel density in thesemi-transparent region 10, and the pixel driving circuit electricallyconnected to the sub-pixels in the first transition region 211 may belocated in the spacing region 11 and the first display region. It shouldbe noted that FIG. 15 does not show the pixel driving circuits connectedto the sub-pixels in the semi-transparent region 10 and the firsttransition region 211. For the connection relationship, reference may bemade to FIG. 12 .

In the following, the first signal line 41 located on the upper side ofthe semi-transparent regions is taken as an example to illustrate thedifference between the structures shown in FIG. 13 and FIG. 15 .Referring to FIG. 15 , the first signal line 41 may include a linesegment 411 disposed on the upper side of one semi-transparent region 10and a line segment 412 disposed on the upper side of the othersemi-transparent region 10. The line segment 411 and the line segment412 may be arranged and electrically connected in a one-to-onecorrespondence, and the two line segments arranged in a one-to-onecorrespondence may be electrically connected to the sub-pixels in a samerow in the spacing region 11 through signal lead wires 40. In oneembodiment, the first signal line 41 may not directly extend from onefirst transition region 211 to another first transition region 211 alongthe first direction D1, but may extend toward the sub-pixels P of thespacing region 11 through the signal lead wires 40, thereby saving acertain space between the two first transition regions 211 arranged inthe first direction. As such, the sub-pixels in the first transitionregion 211 may be easily connected to the pixel driving circuits in thespacing region 11. It should be noted that in the viewing angle of FIG.15 , the arrangement and connection configurations for the first signallines 41 located on the lower side of the semi-transparent regions 10can be referred to the arrangement and connection configurations for thefirst signal liens 41 located on the upper side of the semi-transparentregions 10, and the details will not be repeated here. It should also benoted that FIG. 15 does not show the connection relationship between thefirst signal line 41 and the second signal line 42 in the first displayregion, and for the connection relationship between the first signalline 41 and the second signal line 42, reference may be made to FIG. 13.

Referring to FIG. 15 , the line segments 411 and 412 that are arrangedin a one-to-one correspondence in the first signal line 41 may beelectrically connected to each other and may be connected to a samepixel row in the spacing region 11. FIG. 16 illustrates anotherschematic diagram of a plurality of lead wires located between asemi-transparent region and a transition region and between thesemi-transparent region and a spacing region. Referring to FIG. 16 , inother embodiments, two groups of first signal lines 41 may be providedon the upper side of the semi-transparent region 10. One group of firstsignal lines 41 may be located in the first transition region 211 on theupper side of one semi-transparent region 10, and the other group offirst signal lines 41 may be located in the first transition region 211on the upper side of the other semi-transparent region 10. One group offirst signal lines 41 may be used to electrically connect to theodd-numbered rows of the sub-pixels in the spacing region 11, and theother group of first signal lines 41 may be used to electrically connectthe even-numbered rows of sub-pixels in the spacing region. As such,while providing signals to each row of sub-pixels in the spacing region,the number of first signal lines 41 in the first transition region 211may be reduced. For the detailed connection relationship of the firstsignal lines 41 located on the lower side of the semi-transparent region10, reference may be made to the connection relationship of the firstsignal lines 41 located on the upper side of the semi-transparent region10, and the details will not be repeated here.

FIG. 17 illustrates another schematic diagram of a plurality of leadwires located between a semi-transparent region and a transition regionand between the semi-transparent region and a spacing region. Referringto FIG. 17 , the sub-pixels in a same row in the spacing region 11 maybe at least arranged in a same row as a part of the sub-pixels insemi-transparent region 10. In the spacing region 11, the pixel drivingcircuits 30 corresponding to the sub-pixels that are arranged in a samerow in the spacing region 11 and the semi-transparent region 10 may beelectrically connected to the same first signal line 41. The firstdisplay region AA1 may include a plurality of second signal lines 42extending along the first direction D1 and arranged along the seconddirection D2. At least a part of the sub-pixels in the semi-transparentregion 10 and at least a part of the sub-pixels in the first displayregion AA1 may be arranged in a same row. In the first display regionAA1, the pixel driving circuits 30 corresponding to the sub-pixels thatare arranged in a same row in the first display region AA1 and thesemi-transparent region 10 may be electrically connected to a samesecond signal line 42.

For example, according to various embodiments of the present disclosure,the pixel driving circuits corresponding to the sub-pixels in thesemi-transparent region 10 may be arranged in the first display regionAA1 and the spacing region 11. A part of the sub-pixels in thesemi-transparent region 10 and a part of the sub-pixels in the spacingregion 11 may be arranged in a same row. In the semi-transparent region10 and the spacing region 11, the pixel driving circuits 30corresponding to the sub-pixels arranged in a same row may beelectrically connected to a same first signal line 41. In addition, thepixel driving circuits 30 corresponding to the sub-pixels in the firstdisplay region AA1 may be electrically connected to the second signallines 42, and the second signal lines 42 may provide signals requiredfor the operation of this part of pixel driving circuits. A part of thesub-pixels in the first display region AA1 may be arranged in a same rowwith a part of the sub-pixels in the semi-transparent region 10. In thefirst display region AA1, the pixel driving circuits corresponding tothe sub-pixels in the first display region AA1 and the semi-transparentregion 10 that are arranged in a same row may be electrically connectedto a same second signal line 42. As such, when a signal is provided tothe sub-pixels in the display region, for example, when a gate signal isprovided, the sub-pixels in the same row in the first display regionAA1, the semi-transparent region 10, and the spacing region 11 mayobtain the same gate signal, such that the sub-pixels located in thesame row, as described above, can be illuminated at the same time toavoid picture tearing.

In one embodiment of the present disclosure, referring to FIG. 16 , eachfirst signal line 41 of the plurality of first signal lines 41 may beelectrically connected to a second signal line 43 located on one of thetwo sides of the plurality of first signal line 41 s along the firstdirection D1. That is, the second signal line 42 electrically connecteda first signal line 41 may be located on one side of the first signalline 31 along the first direction D1. As such, the signals transmittedon the first signal line 41 and the second signal line 42 that areelectrically connected to each other may be the same, and a first signalline 41 may be only connected to a second signal line 42 located on oneof the two sides of the first signal line 41 in the first direction D1,such that a signal can be transmitted from the second signal line 42 tothe first signal line 41, and then transmitted to the correspondingpixel diving circuits through a signal lead wire 40. In the viewingangle shown in FIG. 16 , the first signal line 41 located on the upperand lower sides of the left semi-transparent region 10 may beelectrically connected to the odd-number rows of sub-pixels in thespacing region 11, and may also be connected to the second signal lines42 located on the left side of the semi-transparent region 10. The firstsignal line 41 located on the upper and lower sides of the rightsemi-transparent region 10 may be electrically connected to theeven-number rows of sub-pixels in the spacing region 11, and may also beconnected to the second signal lines 42 located on the right side of thesemi-transparent region 10. As such, while ensuring that signals such asgate signals can be provided to the sub-pixels in the spacing region 11,the disclosed display panel may also be conducive to reducing thequantity of the first signal lines 41.

FIG. 18 illustrates a schematic diagram of an exemplary arrangement of asecond transition region, a semi-transparent region, and a spacingregion. Referring to FIG. 18 , the second transition regions 212, thesemi-transparent regions 10, and the spacing region 11 may be arrangedalong the first direction D1. Each semi-transparent region 10 mayinclude a first semi-transparent region 101 and a secondsemi-transparent region 102 arranged along the first direction D1. Alongthe first direction D1, the first semi-transparent region 101 may belocated between the second transition region 212 and the secondsemi-transparent region 102; and the second semi-transparent region 102may be located between the first semi-transparent region 101 and thespacing region 11. The sub-pixels in the first semi-transparent region101 may be electrically connected to the pixel driving circuits 30 inthe second transition region 212, and the sub-pixels in the secondsemi-transparent region 102 may be electrically connected to the pixeldriving circuits 30 in the spacing region 11.

For example, referring to FIG. 18 , in one embodiment of the presentdisclosure, the semi-transparent region 10 may be divided into a firstsemi-transparent region 101 and a second semi-transparent region 102along the first direction D1. The first semi-transparent region 101 maybe located on the side of the second semi-transparent region 102 closeto the second transition region 212, and the second semi-transparentregion 102 may be located on the side of the first semi-transparentregion 101 close to the spacing region 11. When the sub-pixels in thesemi-transparent region 10 are electrically connected to the pixeldriving circuits 30 in the second transition region 212 or in thespacing region 11, the sub-pixels in the first semi-transparent region101 adjacent to the second transition region 212 may be electricallyconnected to the pixel driving circuits 30 in the second transitionregion 212, and the sub-pixels in the second semi-transparent region 102adjacent to the spacing region 11 may be electrically connected to pixeldriving circuits 30 in the spacing region 11. As such, the electricalconnections between the sub-pixels in the semi-transparent region 10 andthe pixel driving circuits 30 outside the semi-transparent region 10 maybe implemented in a close-connection manner, which may be conducive tosimplifying the wiring process and improving the production efficiencyof the display panel 100.

Based on the same principle and concept, the present disclosure alsoprovides a display device. FIG. 19 illustrates a schematic diagram of anexemplary display device according to various embodiments of the presentdisclosure. Referring to FIG. 19 , the display device 200 may include adisplay panel 100 according to various embodiments of the presentdisclosure, and a camera 201. The orthogonal projection of the camera201 on the light-emitting surface of the display panel 100 may belocated in the second display region AA2. It should be noted that forthe embodiments of the display device 200, reference may be made to theembodiments of the display panel 100 provided above, and the detailswill not be repeated here. The display device 200 according to variousembodiments of the present disclosure may include a mobile phone, atablet computer, a television, a monitor, a notebook computer, a digitalphoto frame, a navigator, and any product or component with a displayfunction.

In one embodiment, in one second display region AA2, the display device200 may include a camera corresponding to the two semi-transparentregions 10, or two cameras corresponding to the two semi-transparentregions 10, respectively.

For example, in a display device according to various embodiments of thepresent disclosure, an area corresponding to a second display region AA2may be provided with only one camera, that is, a single camera may bedisposed. At this time, the single camera may correspond to bothsemi-transparent regions 10. In other embodiments, the areacorresponding to a second display region AA2 may be provided with twocameras, that is, a dual-camera arrangement method may be adopted. Atthis time, the two cameras and the two semi-transparent regions 10 maybe arranged in a one-to-one correspondence. A spacing region may beintroduced between the two semi-transparent regions 10, and the pixeldriving circuits corresponding to the sub-pixels in the semi-transparentregion 10 may be arranged in the spacing region 10 and the first displayregion AA1, thereby avoiding the pixel driving circuits 30 correspondingto the sub-pixels in the semi-transparent region 10 from aggregation inthe spacing region 11, which may be conducive to simplifying themanufacturing process for the pixel driving circuits 30 electricallyconnected to the sub-pixels in the semi-transparent region 10 andimproving the production efficiency of the display panel 100 and thedisplay device.

According to the disclosure display panel and display device, thedisplay panel and the display device is provided with a first displayregion and at least one second display region. The first display regionat least partially surrounds the second display region, and the seconddisplay region include at least two semi-transparent regions and aspacing region disposed between the two semi-transparent regions. Duringa display stage, the semi-transparent region and the spacing region inthe second display region both display; and during a picture-takenstage, the semi-transparent region in the second display region servesas a light-transmissive region to implement the photography function.The sub-pixels in the first display region and the second display regionare electrically connected to pixel driving circuits, and the sub-pixelsdisplay can be driven by the pixel driving circuits to display. Further,a spacing region is introduced between two adjacent semi-transparentregions, and at least a part of the pixel driving circuits electricallyconnected to the sub-pixels in the semi-transparent region are disposedin the first display region and the spacing region, thereby avoidingarranging pixel driving circuits in the semi-transparent region and thusaffecting the transmittance of the semi-transparent region. Therefore,the disclosed display panel and display device are conducive toincreasing the light transmittance of the semi-transparent region, andthus are conducive to improving the photographic quality. In addition,the pixel driving circuits electrically connected to the sub-pixels inthe semi-transparent region are partially arranged in the first displayregion, and partially arranged in the spacing region, so that lead wiresconnecting the pixel driving circuits and the sub-pixels in thesemi-transparent region extend to the semi-transparent regionrespectively through the first display region and the spacing region.Therefore, the display panel and display device may be conducive toreducing the layout density of lead wires, which in turn is conducive toreducing the crosstalk between adjacent lead wires in thesemi-transparent region.
